Have you tried disabling the firewall? IIRC, Ajenti has an option to manage firewall rules, so it’s possible that if you’re running, for example, UFW (which uses iptables) and Ajenti uses another, they are conflicting. Just one possible scenario. I’d have to install Ajenti to see as I don’t have an instance spun up for it.

You can check the status of UFW by:

sudo ufw status

If enabled, that’ll give you a list of ports available. If it’s not enabled, you can use the following to enable Port 8000, set the Default Policy to Deny Incoming and then enable UFW. I would also run the following to add your SSH Port so you’re not disconnected:

thanks for your reply I tried creating a new droplet and just installing Ajenti based on the install instructions on there site I also made sure to make sure the 8000 port was enabled in the firewall - same blank page

tried a new droplet with ssh setup and LAMP stack tried to install ajenti again same blank page ?

I am trying to use the latest version of Ubuntu 15.04 I just seem to be going around in circles.
